Patent DE-2826609-A1 (DE)
Title: Incremental impulse generator with timing mark - employing rotating magnets and special alloy detector cores polarised by passage of poles on rotors
Inventor: HAULER PETER DIPL ING
IPC: F02P7/067
Filed: 1978-06-19
Abstract: The pulse generator supplies ignition impulses for an IC. engine. The stator (10) comprises a series of parallel axial wires (11, 12, 13...) of special polycrystalline alloy (Wiegand wire). They are pollarised in one direction or the other by the passage of the magnet poles (19, 20) on the rotor (18). A sharp voltage spike is induced in a winding (17) around the stator each time a wire reverses its magnetic state from one limit to the other. One wire (15) has an additional trigger coil (21) which provides a timing signal for use when setting up the ignition system relative to the engine.

Title: Waste water fluff filter - with rake in granular filter bed for easy backflushing regeneration
Inventor: ANDERL LEOPOLD
IPC: B01D24/46
Filed: 1978-07-17
Abstract: Textile fluff and other particles are removed from waste water in laundries, textile mills and hospitals by a cylindrical vessel with a side inlet on top and a central outlet at the bottom. A filter bed of coarse granules rests on a screen plate and can be stirred by a revolving rake. The latter is driven by a common vertical shaft with a worm conveyor above the bed. This creates a reliable filtering device for coarse impurities such as textile fluff. The filter material is easily regenerated, simply by reversing the direction of flow. Regeneration can be automated as a function of time or pressure.

Title: Evaporating electron beam deflection system - with external magnetic field short circuited by U=bracket
Inventor: KERTESZ GABOR DIPL ING
IPC: H01J37/305
Filed: 1979-05-08
Abstract: A magnetic deflection system for electron beam evaporation sources with deflections of 240-300 degrees employs a main magnetic field, produced across two pole shoes by at least one magnet on the outside of each pole shoe. A U-bracket short-circuits the external magnetic field between these magnets. This reduces the field strength in the neutral magnetic field areas so much that assembly and material selection do not require the extreme care. Several evaporation sources, arranged in a common vacuum chamber, can now be operated independently and without interfering with each other.

Title: Ultrasonic food cooking - by currents at ultrasonic frequency producing thermal in addition to sonotrode energy
Inventor: GRAMBOW JOACHIM DIPL ING
IPC: A23L5/10
Filed: 1979-12-14
Abstract: A cooking process for food uses, in addition to purely thermal energy (resistance heating, infrared grill, microwave energy), a source of mechanical energy, pref. in the ultrasonic frequency range. The purely thermal energy can also be generated by currents of ultrasonic frequency which pass through sonotrodes applied to the food. A pan (2) with a ferromagnetic bottom (3) contg. the food (1) rests on a hotplate (4) above an induction coil (5) which receives currents at ultrasonic frequency from a generator (not shown). The alternating magnetic field (6) produces eddy currents in the bottom (3) to heat it. Ultrasonic energy is transmitted to the food from the top by a sonotrode (7) which is excited by an ultrasonic transducer (8), connected to an ultrasonic generator (not shown). This combines the advantages of the thermal method (appearance and taste) with those of the ultrasonic treatment (preservation of vitamins and nutritive substances, tenderising action).

Title: Quickly kiln-drying green malt - by aerating in esp. impulse-type HF field pref. in two steps
Inventor: KRUEGER ECKHARD PROF DR ING
Filed: 1980-02-26
Abstract: Green malt contg. 40-50wt.% water is kiln-dried by airing in a high frequency field of 10 MHz to 25 GHz (esp. 2-3 GHz) until malt is formed and the water content is reduced to 3-8 wt.%. The high energy treatment pref. takes place in impulses, with rest pauses for airing and cooling between short, high energy treatments. A 2-step process is prefd., in which the water content is reduced to 10-20wt.% at 3-70 deg. C in the 1st "withering" or pre-drying step, and to 3-8wt.% at 75-100 deg. C in the 2nd step. High frequency can be used during both withering and kiln-drying or during kiln-drying alone. The air throughput can be 3500-7000 cu.m./t malt during withering and 500-4000 cu.m/t malt during kiln-drying. High-frequency treatment can reduce kiln-drying time to 1/10 to 1/20 of usual time, without lowering malt quality.
